I have been taking Carbimazole for a while now (say 5-6 weeks) and in the last few days I have developed a sore throat. I am not entirely sure if it is just a cold coming on, although I have no other symptoms. In myself, I feel fine as well. I am just concerned that this might be a side effect of the drug, but I do not want to panic just yet. I have no mouth ulcers either. And I feel fine, I do not feel tired or anything. My next blood test is next Tuesday so do I wait until then to speak to the consultant?
